Question

A network of resistors is connected to a 14 V battery with internal resistance 1 ohm as shown in the circuit
diagram. Calculate (i) equivalent resistance (ii) current in each resistor.​

Answer 1

First, we use Ohm's law ( V = I × R ), to find the current through the resistor. The voltage across the resistor is V = 9 V. The resistance of the resistor is R = 100 Ω. Then, we can use the power rule ( P = I × V ), to find the power dissipated by the resistor.
